tegra-helper-scripts: disable initrd-flash USB instance check

Browse Source 
USB instances might not be consistent between the Jetson boot ROM
and the mass storage USB gadget in the running OS, so make the
cross-check of the instance ID optional, and off by default.

This means that when flashing secureboot-enabled devices using
pre-signed binaries, only one target can be flashed at a time
from a given host.
